samba - Apr 2001 - Samba on multiple subnets

Hi,

The problem as mentioned in the subject is a very short description of the
'real' problem. I'm using samba 2.2a3 (but will upgrade one of these
days to
2.2.0) on a Debian 2.2r3 system. Samba is our domain controller for win9x,
nt and win2k clients.

I've divided our local lan in 4 subnets
(192.168.0.0/192.168.1.0/192.168.2.0/..) to make a difference between the
departments. This way I can also put some limitations on traffic. (filtering
out traffic from subnet x to subnet y for example..) I hope this doesn't
give a high load on our firewall system (= default gateway for all)..

Samba is configured to act as a WINS server. My clients WINS entry point to
the Samba server. It 'seems' to work, I see the machines in the browse
list.
(there's only 1 domain, for all the machines the same one) My problem is now
that on my Samba machine (it's in subnet 0) all works fine. Clients in the 0
subnet also work perfect.

When I do browsing from the other subnets, it also works but goes extremely
slow. (also connecting to the machines to get a view of the shares goes
terribly slow.) It's not fast enough to put it in production, any idea what
might be causing this?

I already went through the browsing text files but can't seem to find an
answer.

If you need any more information (smb.conf), just let me know..

Thanks in advance for any advice,

Kristof Hardy.

Hi Kristof, I suspect a reverse DNS lookup (or
lack thereof) to be the cause in your scenario.
To test, try telnet from one of the slow clients
to the Samba Server. (Do telnet first, don't try
any other connection). If it takes 20+ seconds for
Login screen to come up but performes perfectly
thereafter, then it was probably a name lookup
issue.  The quick workaround is to list your
clients in your Server /etc/hosts file. I think
there might also be a way to proxy your WINS to
DNS, but I don't know how.
